I don't know if this had anything to do with it, but recently I tried to fix a sticky cursor problem and I might have changed something that affected the properties box. While I was searching for my sticky cursor problem, I came across a forum and it recommended to install BitDefender to fix my sticky cursor. I found a free download, so I proceeded to install it and it scanned my system and found 2000+ errors and then it said it fixed 100 of them but then I had to purchase the software to fix the rest. I said "NO" to the purchase but surprisingly, my sticky cursor problem went away.
